Objective: To test the effectiveness of FLASHlite 1001 in orthodontic bracket cementation. Methods: A cordless LED light (FLASHlite 1001 [FL], Discus Dental) was compared with two corded halogen lights (Optilux 501 [OL], Kerr; Ortholux XT [OX], 3M/Unitek). 45 human teeth were embedded in clear acrylic having the facial intact enamel surfaces exposed. Samples were randomly divided into three groups of 15 for each light. All embedded teeth were cleaned with fluoride-free fine pumice, rinsed, acid etched for 20 seconds, rinsed and dried. Orthodontic Brackets (GAC, lower incisor, NY) were cemented to each tooth using Unitek Transbond Primer and Resin Cement (3M/Unitek) according to the manufacturer's instructions. The resin cement was light cured for 20 seconds from the mesial, and 20 sec. from the distal of each bracket. The same operator performed the procedures. Samples were stored in tap water for 24 hours at 37°C. Shear bond testing was performed with a Tinius Olsen Locap Testing Machine (Willow Grove, PA) with 0.005 in/min cross-head speed. A univariate analysis of variance was conducted; Tukey’s-HSD was applied for the multiple comparisons. Results: The statistical analysis revealed significant differences between OX and FL at P<0.06 (FL: 11.18 ± 2.69; OL: 12.02 ± 2.57; OX: 13.73 ± 4.49). Conclusion: Based on this study, FLASHlite 1001 was found to be clinically equivalent to Optilux 501 in orthodontic bonding procedures. Support provided by Discus Dental.
